SAN FRANCISCO -- The San Francisco Giants finally won the National League West without needing to wait for the rival Dodgers' result on the season's final day, pounding the San Diego Padres 11-4 on Sunday for a franchise-record 107th victory to top the 1904 New York team.

Logan Webb did it all in leading surprising San Francisco to its first division crown since 2012, delighting a delirious, deafening crowd of 36,901. Buster Posey had an incredible day, too.

Posey raised both arms into the air when Eric Hosmer struck out swinging to end it, and ran out to the mound to hug reliever Dominic Leone.

"The first thing that comes to mind for me is how proud I am of this group and what they accomplished," Giants manager Gabe Kapler told fans from the field. "Part of the reason that I feel that way is because I think we all knew at the beginning of the season, or even dating back to the beginning of spring training, what the projections are and what the industry sort of thought of us as a club. What I realized is there are some intangibles that those projections and viewpoints failed to take into consideration."

Webb walked off to a roaring standing ovation when replaced in the eighth after allowing three straight singles. He struck out eight and didn't walk a batter while pitching seven-plus stellar innings, and also hit a two-run homer in the fifth to clear the fences for his first time in his career -- a pretty line drive to left.

Posey drove in three runs on a pair of singles and got his 1,500th career hit as San Francisco's division hopes came down to the final day. The Giants clinched the title in Game 162 after losing 3-2 in 10 innings a day earlier as Los Angeles won at night against NL Central champion Milwaukee.

According to ESPN Stats & Information research, the Giants -- who have won 11,301 games in their 139 seasons, the most of any team in MLB history -- had never totaled 107 victories in a season until this year.

The Giants will host the winner of Wednesday night's wild-card game between the Dodgers and Cardinals in Game 1 of an NL Division Series on Friday at Oracle Park. They are assured of facing at least a 90-game winner, as both St. Louis and Los Angeles are not typical wild-card teams. The Cardinals, an afterthought in the race during the summer, strung together 17 straight September wins to force themselves into the equation.

San Francisco wanted to earn it this way to dethrone the reigning World Series champion Dodgers, who could have forced a Monday tiebreaker with a win and a Giants loss. The Dodgers had won the past eight NL West titles since the Giants last did so nine years ago.

San Francisco held baseball's best record for 125 days and won on the last day of the regular season for the first time since 2017.

"This group always thought we were going to win the game. Always," Kapler said.

Manny Machado briefly made things interesting with a sacrifice fly in the fourth against Webb, who went unbeaten since May 5 at Colorado. He finished 10-0 after that loss but was coming off three straight no-decisions since beating the Cubs at Wrigley Field on Sept. 12.

There were so many big hits to back the right-hander's latest gem. Mike Yastrzemski's two-run double in the seventh made it 11-1.

Webb walked to load the bases with one out in the fourth, and Tommy La Stella followed with an RBI single before Wilmer Flores singled in two more runs.

This one brought on some Oct. 3 memories for the storied franchise, now determined to create some more in October like the 2010, '12 and '14 World Series champions with some of the same faces of today in Posey, Brandon Crawford and injured slugger Brandon Belt.

Webb delivered just as Jonathan Sanchez did pitching the Giants past the Padres on the final day in 2010 to advance the club to its first playoff appearance in six years.

Or you could even go way back to Bobby Thomson's "Shot Heard 'Round the World," as Willie Mays and the New York Giants beat Brooklyn 5-4 to clinch the 1951 pennant before eventually losing the World Series.

These 2021 Giants completed a stunning turnaround in manager Kapler's second season from a club that finished 29-31 for third place in the division during the coronavirus-shortened 2020 season.

Los Angeles and these Padres, after all, were the hands-down favorites to win the division when the season began six months ago.

Instead, this might have been Jayce Tingler's final game managing disappointing San Diego (79-83), which had high hopes of contending behind stars Machado and Fernando Tatis Jr. The Padres lost eight of their final nine and finished below .500 for the 10th time in 11 years -- they were 37-23 last year -- after losing 13 of their last 15.

Padres starter Reiss Knehr (1-2) worked three innings in his 12th major league appearance and fifth career start.
